VHT filed a copyright infringement suit against Zillow Group in July 2015, alleging that Zillow had illegally used VHT’s photos on Zillow Digs for its own profit and gain.

The real estate tech giant and photography firm will argue the case in a jury trial starting Jan. 23.

VHT has not named any brokers or MLSs as defendants in this case, but that's not to say that they should consider themselves off the hook in the future.

The list of possible witnesses for both sides contains an array of familiar real estate industry names.

What happens to listing photos displayed on third-party websites after a property sells? Real estate photography company VHT Inc. and real estate technology and media giant Zillow Group are set to square off on that question at trial.
